| 초록 | Molten salt oxidation is one of the most promising alternative to incineration that can be used to oxidatively and efficiently destroy the organic components of mixed and hazardous wastes. The basic concept of molten salt oxidation is to (1) introduce wastes and air into molten salt bed, (2) oxidize organic wastes in the molten salt bed, (3) retain inorganics in the molten salt, and (5) remove the salt for disposal or for processing and recycling. Sodium carbonate(b.p. 850℃) is the typical salt used as the salt. In this of study, pressure fluctuation signals from a molten salt oxidation bed(0.076m I.D.) have been analyzed by adopting the stochastic method to characterize the gas-liquid flow behavior. Effects of input air flow rate(7∼70 l/min) and bed temperature(870∼950℃) on the characteristics of the pressure fluctuation, phase space portraits and Shannon entropy have been studied. It has been found that the phase space portrait, Shannon entropy can be utilized to describe and explain the system turbulence and non-linear dynamic behaviors of gas-liquid flow in molten salt oxidation bed. |
